Nasunin
Nasunin, the antioxidant found in the purple skin of eggplants, is a potent antioxidant and free radical scavenger that has been shown to protect cell membranes from damage. Nasunin helps eliminate the buildup of plaque in the blood vessels, keeping your heart and the cardiovascular system healthy. Roast eggplant slices in the oven with some olive oil to reap this benefit.
